Description
Die Erfindung betrifft eine Stoffmischung als Bindemittel zur Herstellung eines Mörtels. Unter dem Begriff "Mörtel" ist sowohl ein in kleinen Mengen in der Denkmalpflege zum Einsatz kommender Restauriermörtel als auch ein für großflächiges Verputzen einsetzbarer Mörtel zu verstehen.The invention relates to a substance mixture as a binder for producing a mortar. The term "mortar" is to be understood as a restoration mortar used in small quantities in the preservation of monuments as well as a mortar suitable for large-scale plastering.
In der Denkmalpflege besteht ein Bedarf für vielseitig einsetzbare Restauriermörtel, die sich in ihren Eigenschaften an die vom Restaurator vorgefundenen Verwitterungserscheinungen anpassen lassen. So sollten aus optischen Gründen die Korngrößen der Zuschlagstoffe dem Untergrund und dem Umfeld der Antragungen entsprechen. Wesentlich ist jedoch, daß die physikalischen Eigenschaften wie Wasseraufnahme und Wasserabgabe, thermische und hygrische Dehnung und der E-Modul dem Untergrund entsprechen.In the preservation of monuments, there is a need for versatile restoration mortars, which can be adapted in their properties to the weathering phenomena found by the restorer. For optical reasons, the aggregates' grain sizes should correspond to the substrate and the environment of the applications. It is essential, however, that the physical properties such as water absorption and water release, thermal and hygric strain and the modulus of elasticity correspond to the ground.
Typische Einsatzbereiche eines Restauriermörtels sind Antragungen (das Anmodellieren) von Fehlstellen an Figuren und Bauzier aus Naturstein aber auch Abgüsse fehlender Extremitäten bis hin zum Abguß von Skulpturen und Bauteilen. Restauriermörtel kommen in unterschiedlich eingestellter Viskosität darüberhinaus zum Hinterfüllen von Abschuppungen und Abschalungen bei verwittertem Naturstein zum Einsatz.Typical fields of application of a restoration mortar are applications (the modeling on) of defects on figures and Bauzier of natural stone but also casts of missing extremities to the casting of sculptures and components. Restoration mortars come in different viscosity adjusted also used for backfilling of scaling and shuttering in weathered natural stone used.

Die
Weiterhin betrifft die
Aufbauend auf der "Stoffmischung zur Konservierung poröser Stoffe" , Patentanmeldung vom 2.7.2007, haben Versuche zu dem überraschenden Ergebnis geführt, daß diese Stoffmischung bei ausreichend hoher Konzentration - Feststoffabscheidung des Bindemittels zwischen 70 % und 15 %, vorzugsweise zwischen 70 % und 30 % - eine so hohe Bindekraft mit den Silikatoberflächen der mineralischen Zuschlagstoffe aufweisen, daß loser Sand zu einer Art Kunststein mit sehr guten mechanischen Eigenschaften verfestigt werden kann.Based on the "Substance mixture for the preservation of porous substances", patent application of 2.7.2007, experiments have led to the surprising result that this mixture at sufficiently high concentration - solids deposition of the binder between 70% and 15%, preferably between 70% and 30% - Have such a high binding power with the silicate surfaces of the mineral aggregates that loose sand can be solidified into a kind of artificial stone with very good mechanical properties.
Die Variationsbreite der Eigenschaften ist so groß, dass die gefundene Mörtelkombination sich auch zum großflächigen Verputzen als Natursteinimitation und zum dünnflächigen Auftragen auf ein Trägermaterial als Paneel zum Einsatz im Innenund Außenbereich verwenden läßt.The range of variation of the properties is so great that the mortar combination found can also be used for large-scale plastering as a natural stone imitation and for thin-surface application to a carrier material as a panel for use in indoor and outdoor areas.
Wie bei allen Mörteln ist die Qualität des Endproduktes nicht nur von den Eigenschaften und dem Mischungsverhältnis des Bindemittels sondern in starkem Maße von der Qualität und der optimierten Zusammensetzung der Zuschläge hinsichtlich Korngröße und Korngrößenverteilung abhängig. Diese Aussage trifft auch für die hier auf der Basis von Ormosilen als Bindemittel zum Einsatz kommenden Stoffmischungen zu.As with all mortars, the quality of the end product depends not only on the properties and mixing ratio of the binder, but also to a large extent on the quality and the optimized composition of the aggregate size and particle size distribution. This statement also applies to the substance mixtures used here on the basis of ormosils as binders.
Zur Herstellung des Mörtels kann auf den am Markt erhältlichen Abmischungen von Zuschlagstoffen, zurückgegriffen werden. Zusätzlich ist die erreichbare Festigkeit, der Reaktionsablauf und das optische Erscheinungsbild durch die Zusammensetzung der Stoffmischung in einer großen Bandbreite beeinflußbar.For the preparation of the mortar, it is possible to fall back on the mixtures of additives available on the market. In addition, the achievable strength, the reaction sequence and the visual appearance can be influenced by the composition of the composition in a wide range.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß den entsprechenden Mischungen der Zuschlagstoffe ein Bindemittel zugegeben wird, dessen Mischung wenigstens einen Stoff aus der Gruppe der organisch modifizierten Siliziumdioxide insbesondere Organo(alkoxy)silane (Ormosile) enthält.This object is achieved in that the corresponding mixtures of the additives, a binder is added, the mixture contains at least one substance from the group of organically modified silicas, in particular organo (alkoxy) silanes (Ormosile).
Gegenstand der vorliegenden Erfindung ist somit die Verwendung einer flüssigen Stoffmischung als Bindemittel zur Herstellung eines Mörtels, wobei diese Mischung wenigstens einen Stoff aus der Gruppe der organisch modifizierten Siliziumdioxide, insbesondere Organo(alkoxy)silane, enthält, wobei ein Stoff der Mischung ein organisch modifiziertes Siliziumdioxid ist, das wenigstens eine Epoxideinheit enthält und wobei ein Stoff der Mischung ein organisch modifiziertes Siliziumdioxid ist, das mindestens eine Aminfunktion enthält.The present invention thus relates to the use of a liquid mixture as a binder for producing a mortar, said mixture containing at least one substance from the group of organically modified silicas, in particular organo (alkoxy) silanes, wherein a substance of the mixture is an organically modified silicon dioxide which contains at least one epoxide unit and wherein a substance of the mixture is an organically modified silica containing at least one amine function.
Durch unterschiedliche Kombinationen von Organo(alkoxy)silanen und durch Zugabe unterschiedlicher Mengen Alkohol (z.B. Ethanol und Methanol), vorzugsweise Ethanol läßt sich nicht nur die Menge an abgeschiedenem SiO2 beeinflussen und damit die Stabilität des ausreagierten Mörtels, sondern auch die Reaktionszeit steuern. Für das Hinterfüllen von Schalen und Abschuppungen ist dadurch unterschiedliches Fließverhalten gezielt realisierbar. Mit dem Abmischen des Mörtels beginnt die durch Hydrolyse und Polykondensation ablaufende Aushärtung des Bindemittels. Insbesondere bei großvolumigen Antragungen und Abgüssen ist die Aushärtung durch gezielte Temperatur und Feuchteführung überraschend gut steuerbar. Die erfindungsgemäße flüssige Stoffmischung wird als Bindemittel zur Herstellung eines Mörtels verwendet.By different combinations of organo (alkoxy) silanes and by adding different amounts of alcohol (eg ethanol and methanol), preferably ethanol, not only the amount of SiO.sub.2 deposited can be influenced and thus the stability of the reacted mortar, but also the reaction time can be controlled. For the backfilling of shells and peeling different flow behavior can be specifically realized. With the mixing of the mortar begins by hydrolysis and polycondensation proceeding curing of the binder. Especially with large-volume applications and casts, the cure is controlled by targeted temperature and humidity control surprisingly well. The liquid composition according to the invention is used as a binder for the production of a mortar.
